The Impact of Inflammatory Bowel Disease in Canada 2018: Quality of Life

Symptom management experiences of Chinese individuals with Crohn's disease: A longitudinal descriptive qualitative study

Individuals diagnosed with Crohn's disease, a chronic lifelong condition, experience a dynamic or fluctuating process of developing symptom management behavior. However, less clear is how these individuals respond to and manage their symptoms over time. The aim of this study was to longitudinally explore the symptom management experiences of individuals with Crohn's disease in China. A longitudinal qualitative design was used. Eighteen individuals with newly diagnosed Crohn's disease were purposely selected. Semi-structured interviews were conducted on four occasions over a 12-month period. Interviews at each time point were transcribed and coded using conventional content analysis. Afterward, data analyses of each time point were compared longitudinally to form a holistic understanding. Three themes and eight subthemes emerged from the analysis: (1) disclosing symptoms strategically: voluntary disclosure, reluctance to disclose, no need to disclose; (2) decreasing vigilance in symptom prevention: preventing symptoms stringently, preventing symptoms discriminatively, preventing symptoms with decreased diligence; and (3) increasing autonomy in symptom treatment: actively seeking medical advice, self-treatment and self-observation. The participants were inclined to keep symptoms hidden from relatives and friends and showed a downward trend in actively disclosing physical discomfort to medical staff within the course of 1 year. The participants' attention to symptom prevention declined, but the enthusiasm and independence to eliminate symptoms on their own increased over time. Nurses could implement targeted interventions according to the characteristics of different periods to assist individuals with Crohn's disease in managing symptoms effectively, reducing symptom burden and improving their quality of life.

The body as an obstacle and the "other". How patients with chronic inflammatory bowel diseases view their body, self and the good life

BACKGROUND

Treatment of chronic inflammatory bowel disease (IBD) aims to improve patients' quality of life and the extent of treatment success is measured via patient reported outcomes (PROs). However, questionnaires used to collect PROs often include scales that are not specific to IBDs. Improving these scales requires a deeper understanding of patients' lived experience. With this study we give first insights and develop hypotheses on how patients with IBDs experience their body and self and how they adjust their life plans in the context of precision medicine (PM). The guiding question is to understand what they need to achieve a good life, while facing their disease.

METHODS

We developed a conception of the "good life" that draws on Philippa Foot's "naturalized" approach and distinguishes six different dimensions that are relevant for a good life. This conception guided us as we conducted 10 qualitative interviews with patients suffering from IBD who were in precision medicine clinical research settings. The interviews aimed to gain insights for answering our research question: How do body experiences affect the good life of patients with IBD? We analyzed the interviews with interpretative phenomenological analysis (IPA).

RESULTS

Five group experiential themes emerged: (i) Life options and plans, (ii) other people's responses, (iii) strategies to deal with others' responses, (iv) perception of the body and self, and (v) perception of life as good despite suffering. We report here on three of them (i, iv and v), which are primarily relevant for evaluating the outcomes of PM care. Whereas with "life options and plans (i)," our study predominantly confirmed previous research, with "perception of the body and self (iv)," we found that some of the patients changed their relationship to their body and themselves. They perceived the body or the disease as the "other" and their self appears divorced from their own body. Although this might be an avoidance strategy patients use to assign responsibility for their condition and its "disgusting" symptoms to the "other," it is important to include it in patient reported outcome (PRO) assessments.

CONCLUSIONS

We conclude with the insight that the multi-dimensional approach based on Foot's concept of a good life is well-suited as a basis for investigating the quality of life of people with IBD. Interviews based on this concept produced results that go beyond the understanding of health-related quality of life (HRQoL). Additionally, we offer some considerations about patients' opportunities for achieving a good life and suggestions for further developing patient reported outcome scales.

Predictors of Health-Related Quality of Life in Younger Persons With a Fecal Ostomy and Inflammatory Bowel Disease

PURPOSE

The purpose of this study was to determine predictors of health-related quality of life (HRQOL) in persons aged 18 to 40 years living with inflammatory bowel disease (IBD) and a fecal ostomy.

DESIGN

Descriptive cross-sectional study.

SUBJECTS AND SETTING

The sample comprised 98 participants recruited from online discussion boards/support groups for individuals living with IBD and an intestinal ostomy. More than three-quarters (76.5%) were female; 45.9% (n = 44) had lived with an ostomy for 2 years or less. Data were collected through an online survey made available from October 2018 to December 2018.

METHODS

HRQOL was measured using the Healthy Days Core Module (Centers for Disease Control and Prevention HRQOL-4). Item 1 from the CDC HRQOL-4 represented the variable self-rated health (SRH). The subscales of bodily pain, general mental health, and vitality from the Short-Form 36 Health Survey and the subscales of ostomy function and body image/sexuality plus skin irritation item from the Young-Fadok Stoma Quality of Life (QOL) Scale were used to measure predictors of pain, psychological distress, fatigue, peristomal skin irritation, leakage of ostomy appliance, and body image/sexual disturbance. Correlational and hierarchical multiple linear regression analyses were conducted to complete hypotheses testing.

RESULTS

Significant correlations were found between pain, fatigue, peristomal skin problems, psychological distress, SRH, and HRQOL. Pain, fatigue, psychological distress, and self-related health explained 53.2% of the variance in HRQOL based on hierarchical multiple linear regression and controlling for demographic variables such as marital and employment status.

CONCLUSIONS

Findings suggest global disease symptoms of IBD in the form of pain, fatigue, and psychological distress and individual perception of health (SRH) are more important than transient ostomy symptoms of peristomal skin complications and leakage of ostomy appliance in predicting HRQOL. Individuals in this population regularly use online resources indicating a need to understand and gain insight into the information posted online in the management of the fecal ostomy and IBD.

Mental Health Experiences of Adolescents and Young Adults with Inflammatory Bowel Disease During Transition to Adult Care: A Qualitative Descriptive Study

OBJECTIVE

To explore the mental health experiences of adolescents and young adults (AYA) with inflammatory bowel disease (IBD) enrolled in a randomized controlled trial evaluating the impact of a multimodal transition intervention.

STUDY DESIGN

Virtual semistructured interviews were held with 21 AYA aged 16 through 18 years with IBD. Guided by qualitative description, interviews were digitally recorded, transcribed verbatim, and analyzed using an inductive approach to reflexive thematic analysis.

RESULTS

Three themes were generated from the data: (1) a continuum of integration between IBD and personal identity in adolescence and young adulthood; (2) manifestations of the mind-gut connection among AYA with IBD; and (3) hopes and priorities for addressing mental health in IBD care.

CONCLUSIONS

AYA with IBD endorsed the criticality of incorporating mental health discussions into routine care during the transition to adult care, given the co-occurrence of psychosocial stressors throughout this period. A series of factors promoting and hindering the integration of IBD into one's identity were identified and could be explored in clinical encounters.

Exploring the Gut Microbiome's Role in Inflammatory Bowel Disease: Insights and Interventions

Inflammatory Bowel Disease (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC), is a chronic and relapsing inflammatory condition of the intestine that significantly impairs quality of life and imposes a heavy burden on healthcare systems globally. While the exact etiology of IBD is unclear, it is influenced by genetic, environmental, immunological, and microbial factors. Recent advances highlight the gut microbiome's pivotal role in IBD pathogenesis. The microbial dysbiosis characteristic of IBD, marked by a decline in beneficial bacteria and an increase in pathogenic microbes, suggests a profound connection between microbial imbalance and disease mechanisms. This review explores diagnostic approaches to IBD that integrate clinical assessment with advanced microbiological analyses, highlighting the potential of microbiome profiling as a non-invasive diagnostic tool. In addition, it evaluates conventional and emerging treatments and discusses microbiome-targeted intervention prospects, such as probiotics, symbiotics, and faecal microbiota transplantation. The necessity for future research to establish their efficacy and safety is emphasised.

Change in systemic steroid use and surgery rate in patients with inflammatory bowel disease: a Japanese real-world database analysis

BACKGROUND

Corticosteroids are recommended only for induction of remission in inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD). This study aimed to evaluate the change in pharmacologic treatment use, particularly systemic corticosteroids, over approximately 30 years, and the impact of biologics on IBD treatment since their appearance in the 2000s.

METHODS

This retrospective study conducted in Japan used data from the Phoenix cohort database (January 1990 to March 2021). Patients with disease onset at age ≥ 10 years who received treatment for UC or CD between January 1990 and March 2021 were included. Outcome measures were change in IBD treatments used, total cumulative corticosteroid doses, initial corticosteroid dose, duration of corticosteroid treatment, and surgery rate.

RESULTS

A total of 1066 and 579 patients with UC and CD, respectively, were included. In UC, the rate of corticosteroid use as initial treatment was relatively stable regardless of the year of disease onset; however, in CD, its rate decreased in patients who had disease onset after 2006 (before 2006: 14.3-27.8% vs. after 2006: 6.6-10.5%). Compared with patients with disease onset before biologics became available, cumulative corticosteroid doses in both UC and CD, and the surgery rate in CD only, were lower in those with disease onset after biologics became available.

CONCLUSIONS

Since biologics became available, corticosteroid use appears to have decreased, with more appropriate use. Furthermore, use of biologics may reduce surgery rates, particularly in patients with CD. UMIN Clinical Trials Registry; UMIN000035384.

Food-Related Behavioral Patterns in Patients with Inflammatory Bowel Diseases: The Role of Food Involvement and Health Engagement

Nutrition has been acknowledged as crucial in IBD and is relevant to patients' motives behind food choices, which are affected by health engagement (HE) and food involvement (FI). This study aimed to profile IBD patients according to their levels of health engagement and food involvement to identify patterns of different motives behind food choices, particularly regarding the use of food to regulate mood. A cross-sectional study was conducted with 890 Italian IBD patients who completed an online survey in April 2021. We measured health engagement, food involvement, motives behind food choices, emotional states, and food-related quality of life (Fr-QoL). K-means cluster analysis was performed to identify participants with similar levels of health engagement and food involvement. Four clusters were identified: "Health-conscious (high HE, low FI)", "Balanced (high HE, high FI)", "Hedonist (high FI, low HE)", and "Careless (low FI, low HE)". Clusters with high FI are inclined toward seeking pleasurable food, but when supported with high health engagement, individuals were less prone to use food to manage mood. Groups with higher health engagement demonstrated lower hospitalization rates and relapses and better Fr-QoL. Profiling IBD patients regarding FI and HE could aid clinicians in identifying individuals at greater risk of maladaptive food-related behaviors.

Common gastrointestinal symptoms and their impact on psychological state and quality of life in patients with inflammatory bowel disease: a cross-sectional multicenter study in China

Objective

To explore the impact of common gastrointestinal (GI) symptoms on psychological symptoms, sleep quality, and quality of life in patients with inflammatory bowel disease (IBD).

Methods

A unified questionnaire was developed to collect clinical data on the mental psychology and quality of life of IBD patients from 42 hospitals in 22 provinces in P. R. China from September 2021 to May 2022. The general clinical characteristics, psychological symptoms, sleep quality, and quality of life of IBD patients with different numbers of GI symptoms were analyzed by descriptive statistical analysis.

Results

A total of 2,478 IBD patients were finally analysed in this study, including 365 without GI symptoms (14.7%), 752 with single symptoms (30.4%), 841 with double symptoms (33.9%), and 520 with three symptoms (21.0%). Compared with patients without GI symptoms, patients with only simple abdominalgia or diarrhea or hematochezia showed significantly higher levels of anxiety and depression and worse quality of life (all P < 0.05). Compared with asymptomatic patients, patients with double symptoms (e.g. abdominalgia plus hematochezia, diarrhea plus hematochezia, abdominalgia plus diarrhea) and patients with three symptoms (abdominalgia, diarrhea, and hematochezia) showed significantly higher levels of anxiety and depression and worse sleep quality and quality of life (all P < 0.05).

Conclusion

Compared with IBD patients without gastrointestinal symptoms, patients with gastrointestinal symptoms were more likely to experience anxiety, depression, sleep disturbances, and poorer quality of life.

The Interaction between Stress and Inflammatory Bowel Disease in Pediatric and Adult Patients

Background: Inflammatory bowel diseases (IBDs) have seen an exponential increase in incidence, particularly among pediatric patients. Psychological stress is a significant risk factor influencing the disease course. This review assesses the interaction between stress and disease progression, focusing on articles that quantified inflammatory markers in IBD patients exposed to varying degrees of psychological stress. Methods: A systematic narrative literature review was conducted, focusing on the interaction between IBD and stress among adult and pediatric patients, as well as animal subjects. The research involved searching PubMed, Scopus, Medline, and Cochrane Library databases from 2000 to December 2023. Results: The interplay between the intestinal immunity response, the nervous system, and psychological disorders, known as the gut-brain axis, plays a major role in IBD pathophysiology. Various types of stressors alter gut mucosal integrity through different pathways, increasing gut mucosa permeability and promoting bacterial translocation. A denser microbial load in the gut wall emphasizes cytokine production, worsening the disease course. The risk of developing depression and anxiety is higher in IBD patients compared with the general population, and stress is a significant trigger for inducing acute flares of the disease. Conclusions: Further large studies should be conducted to assess the relationship between stressors, psychological disorders, and their impact on the course of IBD. Clinicians involved in the medical care of IBD patients should aim to implement stress reduction practices in addition to pharmacological therapies.

The Impact of the COVID-19 Pandemic on Patients with Ulcerative Colitis: Results from a Global Ulcerative Colitis Narrative Patient Survey

INTRODUCTION

The coronavirus disease 2019 (COVID-19) pandemic created challenges related to disease management of patients with ulcerative colitis (UC).

METHODS

The UC Narrative COVID-19 survey was conducted from August to December 2021 among adults with UC from the United States, Canada, Japan, France, and Finland. Patients were questioned on disease management, health care access and experience, and preferences for interactions with their doctor. Data were analyzed descriptively.

RESULTS

In total, 584 patients qualified for and completed the survey. Compared with 2019, 25% experienced more flares during the pandemic (from early 2020). Most patients (88%) taking prescription medication were very/somewhat satisfied with their current treatment plan; 53% were hesitant to make changes during the pandemic. Factors that patients agreed helped control UC symptoms during the pandemic included fewer social outings (37%), working from home (29%), and less busy schedules (28%). Greater anxiety/stress (43%) and hesitancy to visit a hospital/office (34%) made the control of UC symptoms more difficult. Compared with 2019, more patients relied on certain alternative support systems during the pandemic. Patients who used in-person and virtual appointments were equally very satisfied/satisfied with the quality of care (both 81%). In-person appointments were preferred by 68% of patients when meeting a new doctor, 55% when experiencing a flare, and 52% for regular check-ups; 41% preferred virtual appointments for UC prescription refills.

CONCLUSION

During the pandemic, most patients were satisfied with their current UC treatment plan and access to care; more patients relied on certain alternative UC management support systems, and many were impacted by anxiety/stress.

Older Adults With Inflammatory Bowel Disease in Canada: A Mixed-Methods Exploratory Study of Care Experiences and Health-Related Quality of Life

Literature exploring the health-related quality of life and care experiences of older adults with inflammatory bowel disease is limited despite the increasing prevalence in this population. The purpose of this study was to explore the perceived health-related quality of life and care experiences in older adults with inflammatory bowel disease in Canada. This study used a mixed-methods convergent design consisting of a descriptive, cross-sectional survey and qualitative descriptive interviews. Fifty-eight participants completed the survey and 24 participants completed interviews. Older adults reported satisfaction with inflammatory bowel disease-related care, high levels of disease control, moderate health-related quality of life, and low levels of patient-healthcare team interactions. Themes identified were (1) Experiences of inflammatory bowel disease in daily life; (2) Accessibility of inflammatory bowel disease-related health services; and (3) Communication and relationships to facilitate inflammatory bowel disease care. Ultimately, quality inflammatory bowel disease care for older adults is contingent upon communication between patients and providers, access to multidisciplinary clinics, and support networks. By ensuring these factors are present, providers and patients can work together collectively toward positive patient outcomes, enhanced satisfaction with care, and greater perceived quality of care.

Crohn's disease and clinical management today: How it does?

Crohn's Disease (CD) is an Inflammatory Bowel Disease and is characterized by an immune-mediated nature. Its etiology results from the interaction between genetic, enviromental and microbial factors. Regarding pathophysiology, it involves high levels of interleukin (IL)-12, IL-17, and Th1 profile, along with loss of tolerance mechanisms, an increase in pro-inflammatory interleukins, beyond the possibility to affect any part of the gastrointestinal tract. Its symptoms include abdominal pain, chronic diarrhea, weight loss, anorexia, and fatigue, as well as blood in the stool or rectum. Additionally, conditions comprising musculoskeletal, cutaneous, ocular, hepatic, and hematological alterations may be associated with this scenario and extra-intestinal presentation, such as erythema nodosum, anterior uveitis, osteoporosis, and arthritis can also occur. Today, clinical history, exams as fecal calprotectin, ileocolonocopy, and capsule endoscopy can be performed in the diagnosis investigation, along with treatments to induce and maintain remission. In this sense, anti-inflammatory drugs, such as corticosteroids, immunomodulators, and biological agents, as well as surgery and non-pharmacological interventions plays a role in its therapy. The aim of this review is to bring more current evidence to clinical management of CD, as well as to briefly discuss aspects of its pathophysiology, surveillance, and associated disorders.

Global burden of inflammatory bowel disease 1990-2019: A systematic examination of the disease burden and twenty-year forecast

BACKGROUND

Inflammatory bowel disease (IBD) is an idiopathic intestinal disease with various levels and trends in different countries and regions. Understanding the current burden and trends of IBD in various geographical locations is essential to establish effective strategies for prevention and treatment. We report the average annual percentage change (AAPC) and estimated annual percentage change (EAPC) in age-standardized rates (ASR) of IBD in different regions based on the Global Burden of Disease (GBD) study from 1990-2019, and the relationships between IBD and the human development index (HDI) and socio-demographic index (SDI). The prevalence trends of IBD were predicted by gender from 2019-2039.

AIM

To comprehensively investigate IBD data, providing further insights into the management of this chronic disease.

METHODS

We collected the information on the incidence of IBD from the GBD study from 1990-2019 to calculate the AAPC and EAPC in ASR of IBD in different regions. The relationships between IBD, HDI, and SDI were analyzed. The Nordpred and Bayesian age-period-cohort models were used to predict the prevalence trends of IBD by gender from 2019-2039, and the reliability of the results was validated. Statistics of all the data in this study were performed using R software (version 4.2.1).

RESULTS

North America consistently had the highest IBD ASR, while Oceania consistently had the lowest. East Asia had the fastest average annual growth in ASR (2.54%), whereas Central Europe had the fastest decline (1.38%). Countries with a low age-standardized incidence rates in 1990 showed faster growth in IBD while there was no significant correlation in 2019. Additionally, IBD increased faster in countries with a low age-standardized death rates in 1990, whereas the opposite was true in 2019. Analysis of SDI and IBD ASR showed that countries with a high SDI generally had a higher IBD ASR. Finally, the projections showed a declining trend in the incidence of IBD from 2019-2039, but a gradual increase in the number of cases.

CONCLUSION

As the global population increases and ages, early monitoring and prevention of IBD is important to reduce the disease burden, especially in countries with a high incidence of IBD.

Health Care Disparities, Social Determinants of Health, and Emotional Impacts in Patients with Ulcerative Colitis: Results from a Global Ulcerative Colitis Narrative Patient Survey

BACKGROUND

The Ulcerative Colitis (UC) Narrative global survey assessed aspects of living with UC. This analysis aimed to identify health care disparities, social determinants of health, and emotional impacts related to UC disease management, patient experience, and quality of life.

METHODS

The survey was conducted by The Harris Poll from August 2017 to February 2018 among adults with UC. Responses from 1000 patients in the United States, Canada, Japan, France, and Finland were analyzed based on patient income, employment status, educational level, age, sex, and psychological comorbidities. Odds ratios (ORs) with significant P values (P < .05) from multivariate logistic regression models are reported.

RESULTS

Low-income vs high-income patients were less likely to have participated in a peer mentoring (OR, 0.30) or UC education program (OR, 0.51). Patients not employed were less likely to report being in "good/excellent" health (OR, 0.58) than patients employed full time. Patients with low vs high educational levels were less likely to have reached out to patient associations/organizations (OR, 0.59). Patients aged younger than 50 years vs those aged 50 years and older were less likely to have visited an office within an inflammatory bowel disease center/clinic in the past 12 months (OR, 0.53). Males were less likely to be currently seeing their gastroenterologist than females (OR, 0.66). Patients with vs without depression were less likely to agree that UC had made them more resilient (OR, 0.51).

CONCLUSIONS

Substantial differences in disease management and health care experience were identified, based on categories pertaining to patient demographics and psychological comorbidities, which may help health care providers better understand and advance health equity to improve patient care.

Upadacitinib Induction and Maintenance Therapy Improves Abdominal Pain, Bowel Urgency, and Fatigue in Patients With Ulcerative Colitis: A Post Hoc Analysis of Phase 3 Data

BACKGROUND

This post hoc analysis of a large, phase 3 program evaluated the effects of upadacitinib on fatigue, bowel urgency, and abdominal pain in patients with moderately to severely active ulcerative colitis.

METHODS

Induction data were pooled from 2 identical studies, the U-ACHIEVE induction and U-ACCOMPLISH studies. Patients in these studies received upadacitinib 45 mg once daily or placebo as induction treatment. Responders to induction treatment were rerandomized in the U-ACHIEVE maintenance study to upadacitinib 15 mg once daily, upadacitinib 30 mg, or placebo. The percentage of patients reporting no abdominal pain and no bowel urgency daily via an electronic diary and a meaningful within-person change (≥5 points) in the Functional Assessment of Chronic Illness Therapy-Fatigue score were evaluated.

RESULTS

The results demonstrated a statistically significantly greater percentage of patients reporting no abdominal pain and absence of bowel urgency observed from week 2 (P < .001), with upadacitinib induction treatment and clinically meaningful improvements in Functional Assessment of Chronic Illness Therapy-Fatigue score observed at week 8 (P < .001), when compared with placebo. The maintenance study showed that significant and meaningful improvements in abdominal pain, bowel urgency, and Functional Assessment of Chronic Illness Therapy-Fatigue score achieved during induction were sustained through 52 weeks of maintenance treatment in upadacitinib- vs placebo-treated patients.

CONCLUSIONS

The findings of this study support the additional benefit of upadacitinib in treating moderately to severely active ulcerative colitis by demonstrating a statistically significant impact on clinically meaningful symptoms of fatigue, bowel urgency, and abdominal pain.(U-ACHIEVE induction and maintenance studies; NCT02819635; U-ACCOMPLISH induction study; NCT03653026).

Does probiotic supplementation improve quality of life in mild-to-moderately active ulcerative colitis patients in Jordan? A secondary outcome of the randomized, double-blind, placebo-controlled study

PURPOSE

Recent findings revealed a potential effect of a probiotic in improving quality of life (QoL) in ulcerative colitis (UC). In Jordan, there is scarce data about UC patients and QoL.

METHODS

Twenty-four UC patients were included in the study and were randomly allocated into probiotic (3 × 1010 probiotic capsules containing nine Lactobacillus and five Bifidobacterium species) and placebo control groups (containing polysaccharide supplied in an identical bottle) 3 times daily/6 weeks. A short inflammatory bowel disease questionnaire (SIBDQ) was used to assess the change in the quality of life in both groups at the beginning and the end of the intervention; The study was completed during the COVID-19 pandemic.

RESULTS

Patients treated with probiotics showed a higher score of social (6.92 ± 0.29, p = 0.019), bowel (6.31 ± 0.46, p = 0.001), emotional (6.47 ± 0.46, p < 0.001), and total SIBDQ scores (6.54 ± 0.29, p < 0.001) compared to the placebo group (5.75 ± 1.57, 4.72 ± 1.34, 4.42 ± 1.67 and 4.96 ± 1.27; respectively). Also, the probiotic group had significantly better scores in the systemic, social, bowel, emotional, and total SIBDQ scores in terms of pre- to post-treatment (p < 0.001).

CONCLUSIONS

The use of probiotic therapy containing Lactobacillus and Bifidobacterium species had significantly improved the quality of life among UC patients, this was shown by the improvement in the scores of the systemic domain, social domain, bowel domain, emotional domain, and total SIBDQ. This study is part of a registered study at ClinicalTrials.gov with the number NCT04223479.

Benefits and Challenges of Treat-to-Target in Inflammatory Bowel Disease

There is notable disparity between symptomatology and disease activity in a significant proportion of patients with inflammatory bowel disease (IBD), and escalation of treatment based on symptoms alone can fail to significantly alter the course of disease. The STRIDE-II position statement, published in 2021 by the Selecting Therapeutic Targets in Inflammatory Bowel Disease (STRIDE) initiative of the International Organisation for the Study of IBD (IOIBD) provides the most current recommendations for a treat-to-target (T2T) approach in IBD. Despite the benefits offered by a T2T approach in IBD, there are numerous drawbacks and current limitations to its widespread implementation in real-world clinical practice. Owing to the lack of a standardised definition of MH, outcome data are heterogeneous and limit the comparability of existing data. Further, studies investigating the likelihood of achieving MH with a T2T approach are limited and largely retrospective. Evidence of the real-world feasibility of tight monitoring is currently minimal and demonstrates sub-optimal adherence among patients. Further, the few studies on the acceptability and uptake of a T2T approach in real-world practice demonstrate the need for increased acceptability on both patients' and clinicians' behalf. Real-world applicability is further limited by the need for repeated endoscopic assessments of MH as well as a lack of guidance on how to incorporate the various treatment targets into therapeutic decision-making. We aim to review the benefits and challenges of the T2T approach and to discuss potential solutions to further patient care.

A web-based survey on self-management for patients with inflammatory bowel disease in Japan

BACKGROUND/AIMS

Self-management (SMN) is a recognized component of care for chronic conditions, yet its importance in the context of inflammatory bowel disease (IBD) is unclear. This study evaluates the status of SMN and its relationship with quality of life (QOL) in Japanese patients with IBD.

METHODS

A web-based survey was conducted among adult (≥20 years old) Japanese patients with ulcerative colitis (UC) or Crohn's disease (CD). Registered members of an online IBD information platform completed a 45-item survey covering demographics, diet, treatment, physical condition, stress management, financial concerns, support services, and QOL. SMN was operationally defined by dietary and lifestyle behaviours, and contingency analysis was used to test for associated factors. Individual-level contributions to SMN were identified with logistic regression.

RESULTS

There were 372 responses to the survey (211 with UC, 161 with CD). Approximately 60% of participants practiced SMN and these patients were 4-24% more likely to report positive QOL than those who did not. SMN was more common in patients with CD than those with UC. SMN practice was also associated with IBD-related hospitalisation/surgery and consultation with others about IBD (e.g. physicians, nurses, patients).

CONCLUSIONS

The results of this study suggest an association between the practice of SMN and positive QOL in patients with IBD in Japan.

Complementary and alternative medicine mention and recommendations in inflammatory bowel disease guidelines: systematic review and assessment using AGREE II

BACKGROUND

Many patients with inflammatory bowel disease (IBD) use complementary and alternative medicine (CAM) for disease management. There is, however, a communication gap between patients and healthcare professionals regarding CAM use, where patients are hesitant to disclose CAM use to providers. The purpose of this study was to identify the quantity and assess the quality of CAM recommendations in IBD clinical practice guidelines (CPGs) using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) instrument.

METHODS

MEDLINE, EMBASE, and CINAHL were systematically searched from 2011 to 2022 to find CPGs for the treatment and/or management of IBD. The Guidelines International Network (GIN) and National Center for Complementary and Integrative Health (NCCIH) websites were also searched. Eligible CPGs were assessed using the AGREE II instrument.

RESULTS

Nineteen CPGs made CAM recommendations for IBD and were included in this review. Average scaled domain percentages of CPGs were as follows (overall CPG, CAM section): scope and purpose (91.5%, 91.5%), clarity of presentation (90.3%, 64.0%), editorial independence (57.0%, 57.0%), stakeholder involvement (56.7%, 27.8%), rigour of development (54.7%, 45.9%), and applicability (14.6%, 2.1%).

CONCLUSIONS

The majority of CPGs with CAM recommendations were of low quality and their CAM sections scored substantially lower relative to other therapies in the overall CPG. In future updates, CPGs with low scaled-domain percentages could be improved in accordance with AGREE II and other guideline development resources. Further research investigating how CAM therapies can best be incorporated into IBD CPGs is warranted.

Synthesis, characterization, and molecular modeling of phenylenediamine-phenylhydrazine-formaldehyde terpolymer (PPHF) as potent anti-inflammatory agent

Inflammation, a characteristic physiological response to infections and tissue damage, commences with processes involving tissue repair and pathogen elimination, contributing to the restoration of homeostasis at affected sites. Hence, this study presents a comprehensive analysis addressing diverse aspects associated with this phenomenon. The investigation encompasses the synthesis, spectral characterizations (FT-IR, ¹H NMR, and ¹³C NMR), and molecular modeling of p-phenylenediamine-phenylhydrazine-formaldehyde terpolymer (PPHF), a potent agent in promoting inflammation. To explore the reactivity, bonding nature, and spectroscopy, as well as perform molecular docking for in-silico biological evaluation, density functional theory (DFT) utilizing the def2svp/B3LYP-D3BJ method was employed. The results reveal significant biological activity of the tested compound in relation to anti-inflammatory proteins, specifically 6JD8, 5TKB, and 4CYF. Notably, upon interaction between PPHF and 6JD8, a binding affinity of -4.5 kcal/mol was observed. Likewise, the interaction with 5TKB demonstrated an affinity of -7.8 kcal/mol. Furthermore, a bonding affinity of -8.1 kcal/mol was observed for the interaction with 4CYF. Importantly, these values closely correspond to those obtained from the interaction between the proteins and the standard drug ibuprofen (IBF), which exhibited binding affinities of -5.9 kcal/mol, -7.0 kcal/mol, and -6.1 kcal/mol, respectively. Thus, these results provide compelling evidence affirming the tremendous potential of p-phenylenediamine-phenylhydrazine-formaldehyde (PPHF) as a highly promising anti-inflammatory agent, owing to the presence of nitrogen-a heteroatom within the compound.

"The clumsiness is always present": Parents perspectives of their adolescents with pDCD

AIM

This study elicited the perspectives of parents of adolescents with probable Developmental Coordination Disorder (pDCD) of the implications of DCD on their adolescents' daily-life and the parents' coping strategies and future concerns.

METHODS

Using a phenomenological approach and thematic analysis, we conducted a focus group including 7 parents of adolescents with pDCD aged 12-18 yrs.

FINDINGS

Three major themes emerged from the data: (a) Manifestation and implications of DCD; Parents described the performance challenges and strengths of their adolescents; (b) Discrepancy in perceptions of DCD: Parents described a gap between them and their children's, and between the parents themselves, in their views of the child's difficulties; (c) Diagnosis of DCD and strategies for overcoming its implications: Parents' expressed the pros and cons of labeling and described strategies they used to assist their children.

CONCLUSIONS

It appears that adolescents with pDCD continue to experience performance limitations in daily-life activities, and psychosocial difficulties. Yet, parents and their adolescents do not always view these limitations in a similar manner. Therefore, it is important that clinicians obtain information from both parents and their adolescents'. These results may assist in developing a client-centered intervention protocol for parents and adolescents.

Global, regional and national burden of inflammatory bowel disease in 204 countries and territories from 1990 to 2019: a systematic analysis based on the Global Burden of Disease Study 2019

OBJECTIVES

We aimed to provide the most updated estimates on the global burden of inflammatory bowel disease (IBD) to improve management strategies.

DESIGN

We extracted data from the Global Burden of Disease (GBD) 2019 database to evaluate IBD burden with different measures in 204 countries and territories from 1990 to 2019.

SETTING

Studies from the GBD 2019 database generated by population-representative data sources identified through a literature review and research collaborations were included.

PARTICIPANTS

Patients with an IBD diagnosis.

OUTCOMES

Total numbers, age-standardised rates of prevalence, mortality and disability-adjusted life-years (DALYs), and their estimated annual percentage changes (EAPCs) were the main outcomes.

RESULTS

In 2019, there were approximately 4.9 million cases of IBD worldwide, with China and the USA having the highest number of cases (911 405 and 762 890 (66.9 and 245.3 cases per 100 000 people, respectively)). Between 1990 and 2019, the global age-standardised rates of prevalence, deaths and DALYs decreased (EAPCs=-0.66,-0.69 and -1.04, respectively). However, the age-standardised prevalence rate increased in 13 out of 21 GBD regions. A total of 147 out of 204 countries or territories experienced an increase in the age-standardised prevalence rate. From 1990 to 2019, IBD prevalent cases, deaths and DALYs were higher among females than among males. A higher Socio-demographic Index was associated with higher age-standardised prevalence rates.

CONCLUSIONS

IBD will continue to be a major public health burden due to increasing numbers of prevalent cases, deaths and DALYs. The epidemiological trends and disease burden of IBD have changed dramatically at the regional and national levels, so understanding these changes would be beneficial for policy makers to tackle IBD.

Declining Corticosteroid Use for Inflammatory Bowel Disease Across Alberta: A Population-Based Cohort Study

BACKGROUND AND AIMS

Corticosteroid-free remission is a primary treatment goal in IBD which may be achieved with greater use of anti-TNF therapy. We defined temporal trends of corticosteroid use, anti-TNF use, hospitalization and surgery in a prevalent IBD cohort within the province of Alberta, Canada.

METHODS

Health administrative data were used to identify medication dispensing, hospitalizations and surgery in individuals with IBD from 2010 to 2015. Temporal trends were calculated using log-binomial regression for medications and log-linear models for hospitalizations and surgery rates. Analyses were stratified based on geographic location.

RESULTS

Of 28890 individuals with IBD, 50.3% had Crohn's disease. One in six individuals (15.45%) were dispensed a corticosteroid. Corticosteroid use decreased in both metropolitan areas (AAPC -20.08%, 95% CI: -21.78 to -18.04) and non-metropolitan areas (AAPC -18.14%, 95% CI: -20.78 to -18.04) with a similar pattern for corticosteroid dependence. Corticosteroid dependence was more prevalent in UC vs. CD (P < 0.05), and in the pediatric IBD cohort (13.45) compared to the adult (8.89) and elderly (7.54) cohorts (per 100 prevalent population, P < 0.001). The proportion of individuals dispensed an anti-TNF increased over the study period (AAPC 12.58%, 95% CI: 11.56 to 13.61). Significantly more non-metropolitan versus metropolitan residing individuals were hospitalized for any reason, for an IBD-related, or IBD-specific indication (all P < 0.001) though the proportion requiring IBD surgery was similar between groups.

CONCLUSIONS

An increase in anti-TNF use corresponded to a decline in corticosteroid use and dependence in those with IBD. Inequities in IBD care still exist based on location and age.

Health Care Use and Barriers to Care for Chronic Inflammatory Diseases (CID) among First and Second Generation South Asian Immigrant Children and Parents in Ontario Canada

Although immigrants are disproportionately impacted by growing chronic inflammatory disease (CIDs) rates, yet suffer barriers to access health care, little attention has been given to their primary healthcare or specialist healthcare access as it relates to complex, chronic diseases in Canada, a country with universal health care. This study aims to investigate CID health care use and barriers to care among first- and second-generation immigrant South Asian children and parents in the Greater Toronto Area, Ontario. Drawing on analysis of 24 in depth interviews with children and parents (14 children, 10 parents), the results reveal that although CIDs disproportionately affects South Asian immigrants, they encounter health system, geographic, interpersonal, and knowledge barriers to access requisite care. These barriers exist despite participants having a GP, and are compounded further by limited familial systems, culturally insensitive care, and structural inequities that in some instances make parents choose between health access or other basic needs. Although all participants recognized the importance of specialized care, only 11 participants regularly accessed specialized care, creating new schisms in CID management. The findings suggest that a multisectoral approach that address individual and structural level socio-structural drivers of health inequities are needed to create more equitable healthcare access.

Impact of adalimumab on disease burden in moderate-to-severe ulcerative colitis patients: The one-year, real-world UCanADA study

BACKGROUND

A gap remains in documenting the impact of anti-tumor necrosis factor therapy on disease burden in ulcerative colitis (UC) patients treated in a real-world setting. The use of patient-reported outcomes (PROs) has been discussed as a primary endpoint in the context of the FDA PRO Guidance, for labelling purposes. Specifically, the efficacy and safety of adalimumab have been demonstrated in pivotal trials; however, data are needed to understand how clinical results translate into improvements in key aspects of the daily lives of UC patients, such as symptoms, health-related quality of life (HRQoL), and disability.

AIM

To assess real-world effectiveness of adalimumab on PRO measures in patients with moderate-to-severe UC.

METHODS

UCanADA was a single arm, prospective, 1-year multicenter Canadian post-marketing observational study in which multiple PRO questionnaires were completed—with psychologic distress/depression symptoms as the primary endpoint—by patients with moderate-to-severe UC. Assessments were performed during patients’ routine care visit schedule, which was at the initiation of adalimumab (baseline), after induction (approximately 8 wk), and 52 wk after baseline. Additional optional assessments between weeks 8 and 52 were collected at least once but no more than two times during this period. Serious safety events and per-protocol adverse events were collected.

RESULTS

From 23 Canadian centres, 100 patients were enrolled and 48 completed the study. Measured with the Patient Health Questionnaire–9 items at week 52, 61.5% (40/65) [95% confidence interval (CI): 49.7%-73.4%] of the patients improved in psychologic distress/depression symptoms, which was slightly higher in completers [65.9% (29/44); 95%CI: 51.9%-79.9%)]. At week 52, clinical response and clinical remission were achieved respectively by 65.7% (44/73) and 47.8% (32/73) of the patients. The odds of improving depressive symptoms for those achieving a clinical remission at week 52 was 7.94 higher compared with those not achieving a clinical remission (CI: 1.42, 44.41; P = 0.018). Significant changes from baseline to weeks 8 and 52 were observed in disability, HRQoL, and fatigue. Meaningful improvement was reported in work impairment.

CONCLUSION

At week 52, over 60% of the UCanADA patients had depressive symptoms significantly reduced, as well as HRQoL, fatigue symptoms, and work impairment improved. No new safety signals were detected.

Abdominal Pain in Inflammatory Bowel Diseases: A Clinical Challenge

Up to 60% of inflammatory bowel disease (IBD) patients experience abdominal pain in their lifetime regardless of disease activity. Pain negatively affects different areas of daily life and particularly impacts the quality of life of IBD patients. This review provides a comprehensive overview of the multifactorial etiology implicated in the chronic abdominal pain of IBD patients including peripheral sensitization by inflammation, coexistent irritable bowel syndrome, visceral hypersensitivity, alteration of the brain–gut axis, and the multiple factors contributing to pain persistence. Despite the optimal management of intestinal inflammation, chronic abdominal pain can persist, and pharmacological and non-pharmacological approaches are necessary. Integrating psychological support in care models in IBD could decrease disease burden and health care costs. Consequently, a multidisciplinary approach similar to that used for other chronic pain conditions should be recommended.

Multimodal intervention to improve the transition of patients with inflammatory bowel disease from pediatric to adult care: protocol for a randomized controlled trial

BACKGROUND

Transition in care is defined as the "purposeful and planned movement of adolescents and young adults with a chronic medical condition from pediatric to adult-oriented healthcare systems/care providers." Currently, there are no Level 1 evidence-based interventions to improve the care of transitioning adolescents and young adults (AYAs) with inflammatory bowel disease (IBD). The development of a transition program using a biopsychosocial approach will improve the standards for healthcare delivery to transitioning IBD patients. This is a protocol for a structured randomized controlled trial (RCT) to assess the clinical and implementation effectiveness of a multimodal intervention focused on improving patient function, transition readiness and outcomes among AYA patients with IBD being cared for at pediatric centers in Canada.

METHODS

This multi-center RCT is a type 1 hybrid effectiveness-implementation trial to evaluate effectiveness of the intervention and how it can be implemented more widely after the trial. We will include patients aged 16.0-17.5 years. The intervention program consists of 4 core components: (1) individualized assessment, (2) transition navigator, (3) virtual patient skills-building with a focus on building resilience, self-management and self-efficacy, and (4) a virtual structured education program. The control group will undergo standard-of-care defined by each participating center. The primary outcome will be the IBD Disability Index, a validated measure to assess patient functioning. Secondary outcomes include transition readiness and success, anxiety and depression scales, and health service utilization rates. Additionally, we will measure implementation outcomes and related barriers and facilitators for the intervention program.

DISCUSSION

The type 1 hybrid effectiveness-implementation design will allow for the development of a feasible, sustainable, and acceptable final intervention model. The intervention will consist of modules that can be accessed in an online, virtual platform. The implementation will allow centralization of interventions and funding in order to minimize the impact on local clinical practice or hospital resources. The authors anticipate that the main study limitation will relate to study subjects not completely adhering to every component of the intervention, which will be evaluated and addressed using the implementation science approach.

Prevalence of anxiety and depressive symptoms in ulcerative colitis patients in Jordan and its relationship to patient-reported disease activity

Inflammatory bowel disease is associated with higher rates of anxiety and depression compared to the general population. We aimed to determine the prevalence of anxiety and depressive symptoms among patients with ulcerative colitis and correlation to disease activity. In this cross-sectional study, we collected data from 70 consecutive ulcerative colitis patients over one year at our inflammatory bowel disease outpatient clinic through an interview and a questionnaire containing patient demographics and disease characteristics. Anxiety and depressive symptoms were characterized using the Generalized Anxiety Disorder-7 questionnaire and Patient Health Questionnaire-9, respectively, with ulcerative colitis disease severity assessed by the Partial Mayo scoring system. The majority of our patients were females (68.6%) and the mean age was 39.3 years. Rates of anxiety and depressive symptoms among ulcerative colitis patients were 65.7% and 58.6%, respectively. Depressive symptoms were significantly associated with patient-reported disease activity (r = 0.361; p = 0.010). Significant percentages of ulcerative colitis patients were appreciated to have anxiety and depressive symptoms, and there was a correlation between patient-reported disease activity and depressive symptoms. At this high rate of prevalence, it is justified to screen patients for the presence of psychiatric comorbidities.

Impact of the Coronavirus Disease Pandemic on Health-Related Quality of Life of Patients with Inflammatory Bowel Disease

BACKGROUND

To learn from the crisis caused by the coronavirus disease (COVID-19) pandemic and be prepared for future pandemics, it is important to investigate the impact of this period on the wellbeing of patients with inflammatory bowel disease (IBD).

AIMS

To describe the health-related quality of life (HRQoL) and disease control of IBD patients during the first wave of the COVID-19 pandemic in The Netherlands.

METHODS

Between March 17 and July 1, 2020, patients aged 18 years and older with IBD from the Erasmus MC (Rotterdam, The Netherlands) were invited to complete online questionnaires at week 0, 2, 6 and 12. The Inflammatory Bowel Disease Questionnaire (IBDQ), the Inflammatory Bowel Disease Control-8 (IBD-control-8) and the numeric rating scale on fatigue were used. The evolution of the different outcomes over time was measured using mixed models.

RESULTS

Of 1151 invited patients, 851 patients (67% CD and 33% UC or IBD-U) participated in the study (response rate 74%). No relevant changes in total scores were found over time for the IBDQ (effect estimate 0.006, 95% CI [- 0.003 to 0.015]) and IBD-control-8 (effect estimate 0.004, 95% CI [0.998-1.011]). There was a slight, increasing trend in fatigue scores over time (effect estimate 0.011, 95% CI [0.004, 0.019]).

CONCLUSIONS

This first lock down due to the COVID-19 pandemic in The Netherlands did not impact on the HRQoL and disease control of patients with IBD. Up to date information may have contributed to a stable HRQoL in IBD patients even in an extreme period with restrictions and insecurities.

Crohn’s disease (CD) is associated with reduced quality of life, increased absenteeism and high direct medical costs resulting from frequent hospitalizations and surgeries. Tumor necrosis factor–alpha inhibitors (TNFi’s) have transformed the therapeutic landscape and enabled a shift from a symptom control to a treat-to-target strategy. The Effect of Tight Control Management on Crohn’s Disease (CALM) trial demonstrated tight control (TC), with TNFi dose changes informed by biochemical markers of inflammation, achieved higher mucosal healing rates compared with conventional management (CM) based on symptoms. A Markov model compared TC and CM strategies from the perspective of the Canadian public payer using patient-observation data from the CALM trial. A regression model estimated weekly CD Activity Index–based transition matrices over a 5-year horizon and included covariates to improve extrapolation of outcomes beyond the 48-week trial assessment period. Costs of CD-related hospitalizations, biomarker tests and adalimumab injections were sourced from public data. Other direct medical costs, quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs) were calculated. Absenteeism was monetized and included in a sensitivity analysis. Over the 5-year time horizon, TC reduced hospitalization costs by 64% compared with CM. Other direct medical costs were reduced by 22%; adalimumab costs increased by 38%, generating an ICER of $35,168 per QALY gained. Absenteeism costs were reduced by 54%, and, when that was included in the model, TC became dominant compared with CM. Management of CD with TC is cost-effective compared with CM in Canada and is dominant if indirect costs associated with absenteeism are included. Trial registration number: NCT01235689.

OUP accepted manuscript

Background

Canada has among the highest incidence and prevalence rates of inflammatory bowel disease (IBD) in the world. While access to IBD specialty care can have a direct impact on health-related outcomes, the complexity of accessing IBD specialty care within Canada is not well understood and presents a barrier to implementation and evaluation of IBD specialty care.

Aim

The IBD Summit was held in partnership with Crohn’s & Colitis Canada to identify barriers and facilitators of IBD specialty care by exploring the perceptions and experiences of key stakeholders of IBD care across Canada.

Results

A total of 20 key stakeholders attended, including gastroenterologists, patients, researchers and policymakers. Perceptions and experiences of stakeholders were transcribed, coded and thematically analyzed. Three key categories relating to access to IBD care arose: (1) inadequate system structure, (2) process inefficiencies and (3) using outcomes to guide system change. The IBD Summit identified similar perceptions and experiences among stakeholders and across provinces, highlighting common barriers and facilitators that transcended provincial and health care system boundaries.

Conclusions

Key suggestions identify the clinical importance of comprehensive integrated multidisciplinary care approaches with enhanced communication between patient and health care providers, greater information sharing among team members, streamlined referral and triage processes, and improved incorporation of best practice into clinical care. Stakeholders across Canada and in other countries may benefit from the suggestions presented herein, as well as the successful use of collaborative and inclusive methods of gathering the perceptions and experiences of key stakeholders from diverse backgrounds.

Intravenous versus subcutaneous delivery of biotherapeutics in IBD: an expert's and patient's perspective

Several biologic treatments are available in addition to intravenous also in subcutaneous form for treatment of chronic diseases. Benefits of the subcutaneous application of drugs include self-administration by the patient, shorter time of application process with less infusion related adverse events and consequently lower healthcare costs. With appropriate education and support patients are able to administer their treatments at home. This leads to improvement of quality of life, reduction of time needed to travel to the healthcare institution and consequently also reduces costs also for the patient.

Over one million residents in the USA and 2.5 million in Europe are estimated to have inflammatory bowel disease (IBD), with substantial costs for health care. These estimates do not factor in the ‘real’ price of IBD, which can impede career aspirations, instil social stigma and impair quality of life in patients.

The Virtual Community Meeting, which offered an exchange of experience and opinions from healthcare professionals who are active in treating IBD, and patients with this chronic disease, revealed in-depth arguments and answers to some essential questions: which patients prefer subcutaneous over intravenous dosing; which patients continue to favour intravenous infusions; what are the limitations regarding both applications; what is the patient’s role in therapeutical decision-making and how does IBD affect the patient’s work, finances and quality of life? The aim of this article is to discuss the differences between subcutaneous and intravenous dosing from the health-economic, scientific, and personal perspectives.

The meeting offered strong confirmation that most of the patients and healthcare professionals prefer subcutaneous over intravenous drug administration but emphasise the management of risks associated with treatment compliance. Patient education provided by the IBD team in this regard is mandatory. Quality of life of patients is poorer during active disease, but the findings that it can improve over time, including as a result of home- or self-administration of biologics, may be encouraging for individuals with this chronic disease.

Associations between Multimorbidity Patterns and Subsequent Labor Market Marginalization among Refugees and Swedish-Born Young Adults-A Nationwide Registered-Based Cohort Study

Background: Young refugees are at increased risk of labor market marginalization (LMM). We sought to examine whether the association of multimorbidity patterns and LMM differs in refugee youth compared to Swedish-born youth and identify the diagnostic groups driving this association. Methodology: We analyzed 249,245 individuals between 20–25 years, on 31 December 2011, from a combined Swedish registry. Refugees were matched 1:5 to Swedish-born youth. A multimorbidity score was computed from a network of disease co-occurrences in 2009–2011. LMM was defined as disability pension (DP) or >180 days of unemployment during 2012–2016. Relative risks (RR) of LMM were calculated for 114 diagnostic groups (2009–2011). The odds of LMM as a function of multimorbidity score were estimated using logistic regression. Results: 2841 (1.1%) individuals received DP and 16,323 (6.5%) experienced >180 annual days of unemployment during follow-up. Refugee youth had a marginally higher risk of DP (OR (95% CI): 1.59 (1.52, 1.67)) depending on their multimorbidity score compared to Swedish-born youth (OR (95% CI): 1.51 (1.48, 1.54)); no differences were found for unemployment (OR (95% CI): 1.15 (1.12, 1.17), 1.12 (1.10, 1.14), respectively). Diabetes mellitus and influenza/pneumonia elevated RR of DP in refugees (RRs (95% CI) 2.4 (1.02, 5.6) and 1.75 (0.88, 3.45), respectively); most diagnostic groups were associated with a higher risk for unemployment in refugees. Conclusion: Multimorbidity related similarly to LMM in refugees and Swedish-born youth, but different diagnoses drove these associations. Targeted prevention, screening, and early intervention strategies towards specific diagnoses may effectively reduce LMM in young adult refugees.

Emerging Comorbidities in Inflammatory Bowel Disease: Eating Disorders, Alcohol and Narcotics Misuse

Inflammatory bowel disease (IBD) is a chronic and potentially devastating condition of the digestive tract which is exemplified by increasing prevalence worldwide, byzantine pathogenesis with a poorly defined role of the environmental factors, and complex clinical demonstration. As a systemic disease, IBD may progress with a wide spectrum of extraintestinal manifestations (EMs) and comorbidities affecting different organs and systems, from anaemia, undernutrition, and cancer to those which are often neglected like anxiety and depression. Evolving IBD epidemiology and changing environment are reflected by an expanding list of IBD-related comorbidities. In contrast to the well-established role of smoking the connection between alcohol and IBD is still debatable on many levels, from pathogenesis to complications. Furthermore, little is known about narcotics use in IBD patients, even if there are obvious factors that may predispose them to narcotics as well as alcohol misuse. Last but not least, the question arises what is the prevalence of eating disorders in IBD. In our paper, we aimed to discuss the current knowledge on alcohol and drugs misuse and eating disorders as emerging extraintestinal comorbidities in IBD.

The inflammatory bowel disease disk application: A platform to assess patients' priorities and expectations from treatment

OBJECTIVE

Inflammatory bowel disease (IBD) significantly impacts on patients' well-being. Patients' preferences for treatment outcomes do not necessarily fit physicians' goals. We aimed to investigate patients' priorities and expectations from treatment.

METHODS

A questionnaire based on the IBD Disk application was distributed to patients through social media. Patient's preferences were assessed by grading the 10 IBD Disk items on a Likert-type scale from 1 to 10. A cluster analysis was used to classify patients into homogeneous subgroups according to their preferred items, using the K-means method.

RESULTS

Among the 224 patients, 69.2% had Crohn's disease (CD). Their mean age was (38.9 ± 14.9) years and 62.9% were female. More CD patients compared with those with ulcerative colitis were treated with biologics compared with those with ulcerative colitis (71.0% vs 39.1%, P < 0.001). Most IBD Disk items ranked high in patients' preferences for treatment outcomes. Their leading preference was reducing abdominal pain, which was more prominent in CD patients, followed by regulating defecation and energy. Least important were interpersonal interactions, sexual functions, and body image. Patients were categorized into three clusters. Cluster 3 patients gave lower scores to most items and were characterized by tertiary education (P = 0.001), higher income (P < 0.001), less active disease (P = 0.02), and higher prevalence of successful treatment (P = 0.04).

CONCLUSIONS

Patients' preferences for treatment outcomes are influenced by higher education, higher income, rural-dwelling, and disease activity. Better understanding of individual patient's preferences and the factors that affect them might bridge the gap between patients' and physicians' priorities to achieve better teamwork in controlling disease outcomes.

Ulcerative Colitis Narrative findings: Australian survey data comparing patient and physician disease management views

Background and Aim

The Global Ulcerative Colitis (UC) Narrative Survey aimed to evaluate the impact of UC, perceptions of UC burden, and management approaches. Here, we present data from patients and physicians in Australia.

Methods

Surveys, fielded by The Harris Poll, were completed by 215 patients with UC and 90 physicians, between August 2017 and February 2018. Surveys included questions on disease characteristics, impact on life, communication with physicians, and patient knowledge of UC. Results are presented descriptively from all respondents (with no imputation for missing data).

Results

Based on medication history, 84% of patients had moderate to severe UC. Diagnostic delay was on average 1.9 (SD 5.0) years and 48% of patients had waited ≥1 year for diagnosis. Nearly two‐thirds (65%) of patients considered themselves to be in remission, with 97% also reporting a flare in the past year. The majority (92%) of patients were satisfied with their UC medication and, if their treatment made them feel “good enough,” many (75%) would not consider an alternative. Most (90%) patients were satisfied with communication with their physician; however, only 48% felt comfortable raising emotional concerns. Both patients and physicians desired more time during routine appointments. Patients had gaps in their knowledge of UC, which physicians mostly recognized.

Conclusions

The Australian survey results highlighted the diagnostic delay and burden of UC patients' experience, gaps in patients' knowledge of UC, and challenges in patient–physician communication. Compared with the overall Global UC Narrative Survey, patients in Australia reported a high burden of disease.

Novel Approaches Identifying Relevant Patient-Reported Outcomes in Patients With Inflammatory Bowel Diseases-LISTEN 1

Background

Several patient-reported outcomes (PROs) have been established and are widely used in the assessment of patients with inflammatory bowel disease (IBD). However, it has never been investigated which PRO items are experienced by and are considered most relevant for IBD patients.

Methods

A review of IBD-related disease scores by a steering committee led to the identification of relevant PRO questions and assignment to 16 different PRO categories (9 symptoms and 7 impacts) that characterize patient's disease burden. In a cross-sectional study, a digital patient survey was carried out to determine the self-reported experience by multiple response, the relevance of these PRO categories by pairwise comparison and the suitability of the respective questions and answer possibilities by yes-or-no-question.

Results

Sixty patients with Crohn's disease (CD) (56.7% women; mean age 40.6 years; mean disease duration 12.4 years) and 60 patients with ulcerative colitis (UC) (51.7% women; mean age 37.3 years; mean disease duration 9.0 years) participated in the patient survey. All predefined symptoms and impacts, with the exception of nausea, were experienced by at least 50% of patients. Stool urgency and pain were rated the 2 most important symptoms in CD patients with similar ratings for relevance. Stool urgency was also the most important symptom in patients with UC, followed by stool frequency. Differences in self-reported experience between CD and UC patients were seen for the symptoms of rectal bleeding, pain, and nausea. Most important impact of symptoms in both patient groups were general wellbeing followed by social activities, while sexual activity was the least relevant impact category.

Conclusions

Stool urgency was the most relevant and most self-reported symptom for both CD and UC. Relevance and self-reported experience of pain and rectal bleeding differed between the 2 diseases. Therefore, the future collection of PROs should take these disease specificities into consideration.

Anti-TNF and immunosuppressive combination therapy is preferential to inducing clinical remission in patients with active inflammatory bowel disease: A systemic review and meta-analysis

OBJECTIVE

To compare the efficacy and safety of a combination therapy of biologics and immunosuppressants with biological monotherapy in inflammatory bowel disease (IBD) in a systematic review and meta-analysis.

METHODS

Eligible randomized controlled trials (RCTs) on the comparison of the efficacy and safety of biologics and immunomodulators with biological monotherapy were identified from the EMBASE, PubMed and the Cochrane Library databases published up to 1 May 2020. Raw data were extracted, pooled relative risk (RR) and 95% confidence interval (CI) was calculated, the fixed-effect and inverse variance models were used. Funnel plots were performed to analyze publication bias.

RESULTS

Twelve RCTs were eligible for analysis. Overall, there was statistically a benefit for combination treatment over biologic monotherapy (IFX/ADA) in inducing clinical remission and preventing relapse in patients with IBD (RR 0.89, 95% CI 0.80-0.98). Moreover, the combination therapy was superior to biological monotherapy for active CD (RR 0.83, 95% CI 0.73-0.94). Also, there were significant benefits for combination therapy in the subgroup treated with infliximab (IFX) (RR 0.83, 95% CI 0.70-0.97).

CONCLUSIONS

Combination therapy has slight benefits in inducing clinical remission in active CD compared with biological monotherapy. Patients with IBD who receive therapy with IFX and immunomodulator also have a mild advantage in comparison with those treated with IFX monotherapy.

Exogenous l-fucose protects the intestinal mucosal barrier depending on upregulation of FUT2-mediated fucosylation of intestinal epithelial cells

FUT2, a protein that uses l-fucose to mediate fucosylation of intestinal epithelial cells, is one of the detected gene variants in IBD patients. We aimed to investigate whether exogenous l-fucose could be an enteral nutritional supplement to protect intestinal barrier function. The effect of l-fucose on the restoration of epithelial barrier function in both the DSS-induced colitis mouse model and LPS-stimulated Caco-2 cells was investigated, and the impact on fucosylation of epithelial cells was examined. The severity of DSS-induced colitis was significantly reduced by l-fucose. Restoration of epithelial barrier function by l-fucose was detected. Direct l-fucose-mediated protection of tight junctions was observed in Caco-2 cells. Moreover, exogenous l-fucose promoted the exogenous metabolic pathway of l-fucose, and fucosylation of epithelial cells both in vivo and in vitro. Moreover, knockout of the FUT2 gene restrained fucosylation and the protective effect of l-fucose on barrier function. The severity of colitis was not improved by l-fucose in Fut2 knockout mice. Therefore we conclude that exogenous l-fucose protects intestinal barrier function and relieves intestinal inflammation via upregulation of FUT2-mediated fucosylation of intestinal epithelial cells.

Effectiveness and safety of adalimumab biosimilar ABP 501 in Crohn's disease: an observational study

BACKGROUND AND OBJECTIVE

there are no studies in the literature about the effectiveness of adalimumab biosimilar ABP 501 in Crohn's disease. The aim of this study was to evaluate its effectiveness and safety.

METHODS

an observational study was performed in Crohn's disease patients treated with ABP 501, with the classic induction and maintenance regimen and in Crohn's disease patients who were switched from the adalimumab originator to ABP 501.

RESULTS

eighty-seven patients were included in the study, of which 25 were naïve to the adalimumab originator and 62 were switched to ABP 501. In adalimumab-naïve patients, clinical response at three months was 60% (15/25) and clinical remission at three months was 56% (14/25). At six months, 95.2% (59/62) of the patients switched to ABP 501 were still in therapy, without a significant increase of clinical activity (Harvey-Bradshaw index from 3.4, 95% CI = 2.4-4.4, to 3.8, 95% CI = 2.7-4.9, p = 0.23) and inflammatory biomarkers (C-reactive protein from 4.2 mg/l, 95% CI = 2.5-5.9 mg/l, to 3.6 mg/l, 95% CI = 2.2-5 mg/l, p = 0.32). There were no unexpected adverse events during the study period.

CONCLUSIONS

our results support ABP 501 as an effective and well-tolerated drug, with a good interchangeability with its originator for the treatment of Crohn's disease.

Food-related quality of life in adults with inflammatory bowel disease is associated with restrictive eating behaviour, disease activity and surgery: A prospective multicentre observational study

BACKGROUND

Measuring food-related quality of life (FRQoL) quantifies the psychosocial impact of eating and drinking. FRQoL and associated factors are not well explored in people with inflammatory bowel disease (IBD), despite IBD being a chronic disease affecting the digestive tract. The present study aimed to characterise and identify any patient or disease-related predictors of FRQoL in individuals with IBD.

METHODS

Adults with a formal diagnosis of IBD were recruited to a prospective multicentre cross-sectional study between April 2018 and December 2019. Participants completed questionnaires measuring FRQoL (FRQoL-29), clinical disease activity (Harvey Bradshaw Index and Simple Clinical Colitis Activity Index), restrictive eating behaviour (Nine-Item Avoidant/Restrictive Food Intake Disorder Screen), mental health (Depression Anxiety Stress Scale-21) and other patient and disease-related variables. A multivariable regression was performed to identify factors associated with FRQoL.

RESULTS

One hundred and eight participants completed the questionnaires (n = 39, Crohn's disease; n = 69, ulcerative colitis). The mean FRQoL was 79 (95% confidence interval = 75-84) (poor, 0; superior, 145). Poorer FRQoL was observed in those with restrictive eating behaviour associated with fear of a negative consequence from eating (p < 0.0001) and reduced appetite (p < 0.030). Greater FRQoL was observed in those with lower disease activity (p < 0.0001) and previous IBD surgery (p = 0.024). FRQoL was not associated either way by IBD phenotype, duration, or gender. The majority of participants obtained their dietary information from the internet (60%) or gastroenterologist (46%).

CONCLUSIONS

FRQoL in people with IBD is poorer in those with restrictive eating behaviours and clinically active disease. Interestingly, it was greater in those with previous IBD surgery. Further research is required to validate these associations and explore longitudinal effects of poor FRQoL on patient outcomes and potential strategies for prevention or management of impaired FRQoL in IBD.

The Effect of Psychotherapy on Quality of Life in IBD Patients: A Systematic Review

BACKGROUND

Patients with inflammatory bowel disease (IBD) express a need for additional psychotherapy; however, psychological support is not incorporated in the routine care of persons with IBD. This systematic review aims to assess the effect of psychotherapy on quality of life (QoL).

METHODS

A systematic search was conducted on October 7, 2019, using Embase, Medline (Ovid), PubMed, Cochrane, Web of Science, PsycInfo, and Google Scholar to collect all types of clinical trials with psychotherapeutic interventions that measured QoL in patients with IBD aged ≥18 years. Quality of evidence was systematically assessed using the Grading of Recommendations Assessment, Development, and Evaluation criteria.

RESULTS

Out of 2560 articles, 31 studies (32 articles) were included with a total number of 2397 patients with active and inactive IBD. Of the 31 eligible studies, 11 reported a significant positive effect and 6 had ambiguous results regarding the impact of psychotherapeutic interventions on QoL. Treatment modalities differed in the reported studies and consisted of cognitive-behavioral therapy, psychodynamic therapy, acceptance and commitment therapy, stress management programs, mindfulness, hypnosis, or solution-focused therapy. All 4 studies focusing on patients with active disease reported a positive effect of psychotherapy. Trials applying cognitive-behavioral therapy reported the most consistent positive results.

CONCLUSIONS

Psychotherapeutic interventions can improve QoL in patients with IBD. More high-quality research is needed before psychological therapy may be implemented in daily IBD practice and to evaluate whether early psychological intervention after diagnosis will result in better coping strategies and QoL throughout life.

Comorbid anxiety-like behavior in a rat model of colitis is mediated by an upregulation of corticolimbic fatty acid amide hydrolase

Peripheral inflammatory conditions, including those localized to the gastrointestinal tract, are highly comorbid with psychiatric disorders such as anxiety and depression. These behavioral symptoms are poorly managed by conventional treatments for inflammatory diseases and contribute to quality of life impairments. Peripheral inflammation is associated with sustained elevations in circulating glucocorticoid hormones, which can modulate central processes, including those involved in the regulation of emotional behavior. The endocannabinoid (eCB) system is exquisitely sensitive to these hormonal changes and is a significant regulator of emotional behavior. The impact of peripheral inflammation on central eCB function, and whether this is related to the development of these behavioral comorbidities remains to be determined. To examine this, we employed the trinitrobenzene sulfonic acid-induced model of colonic inflammation (colitis) in adult, male, Sprague Dawley rats to produce sustained peripheral inflammation. Colitis produced increases in behavioral measures of anxiety and elevations in circulating corticosterone. These alterations were accompanied by elevated hydrolytic activity of the enzyme fatty acid amide hydrolase (FAAH), which hydrolyzes the eCB anandamide (AEA), throughout multiple corticolimbic brain regions. This elevation of FAAH activity was associated with broad reductions in the content of AEA, whose decline was driven by central corticotropin releasing factor type 1 receptor signaling. Colitis-induced anxiety was reversed following acute central inhibition of FAAH, suggesting that the reductions in AEA produced by colitis contributed to the generation of anxiety. These data provide a novel perspective for the pharmacological management of psychiatric comorbidities of chronic inflammatory conditions through modulation of eCB signaling.

Prevalence of depression and anxiety in people with inflammatory bowel disease and associated healthcare use: population-based cohort study

BACKGROUND

Inflammatory bowel disease (IBD) has a significant impact on quality of life for many people.

OBJECTIVE

To assess the prevalence of common mental health conditions in IBD and the combined impact of IBD and mental health conditions on healthcare use and time off work.

METHODS

A UK population-based primary care database (Royal College of General Practitioners Research and Surveillance Centre) was used to identify adults with IBD (n=19 011) (Crohn's disease (CD) or ulcerative colitis (UC)), and matched controls (n=76 044). Prevalences of anxiety, depressive episodes and depressive disorder recorded in primary care were assessed between 2016 and 2018. Outcomes comprised of rates of primary care visits, emergency secondary care visits, certificates for time off work, antidepressant and anxiolytic prescriptions.

FINDINGS

Mental health conditions were more common in people with CD than controls: anxiety episodes (3.5% vs 3.0%; p=0.02), depressive episodes (5.7% vs 4.1%; p<0.001) and depressive disorder (17.5% vs 12.9%; p<0.001), and people with UC versus controls: depressive episodes (4.4% vs 3.6%; p<0.001) and depressive disorder (14.2% vs 12.4%; p<0.001). Healthcare utilisation rates were higher in people with IBD than controls (primary care visits incidence rate ratio 1.47 (95% CI 1.43 to 1.51); emergency secondary care visits 1.87 (1.79 to 1.95); fitness for work certificates 1.53 (1.44 to 1.62); antidepressant use 1.22 (1.13 to 1.32); anxiolytic use 1.20 (1.01 to 1.41)). In people with IBD, mental health conditions were associated with additional increases in healthcare use and time off work.

CONCLUSION

Depression and anxiety are more common in people with IBD than matched controls. Healthcare utilisation and prescribing of psychotropic medications are also higher in people with IBD. Mental health conditions in people with IBD are associated with additional healthcare use and time off work.

CLINICAL IMPLICATIONS

Evidence-based mental health support programmes, including psychological treatments, are needed for people with IBD.

Patient perceptions of current and potential inflammatory bowel disease diagnostic and monitoring tests

BACKGROUND

Less invasive inflammatory bowel disease (IBD) tests are increasingly being incorporated into clinical practice as adjuncts to endoscopy to monitor disease activity and guide optimal care. Little is known about patient perspectives of these tests.

AIMS

To assess patient perspectives of the current IBD tests and potential future tests, such as saliva, urine or breath.

METHODS

New Zealand adults with IBD were invited to complete an anonymous online survey. Experiences relating to blood or faecal tests, medical imaging (abdominal ultrasound, abdominal computerised tomography and magnetic resonance enterography) and colonoscopy were collected.

RESULTS

Of the 117 completed surveys, 112 respondents provided background details. The majority (85%) of participants were female and 88% were under 55 years of age with a mean disease duration of 8.98 years. General blood tests were reported as the most prescribed, completed, comfortable test and the least worrying test results. Imaging tests were reported as the least ordered and the most refused tests. Colonoscopy was rated as the least comfortable and generated the most worry. Test explanations by a referring clinician significantly impacted on respondents' levels of understanding across all tests, but did not affect the level of worry when receiving test results. Saliva, blood and breath tests were chosen as the most preferred disease monitoring tests.

CONCLUSION

Patients with IBD preferred any tests less invasive than colonoscopy. An explanation by referring doctor enhanced patients' understanding, but did not necessarily influence their level of comfort or worry. This article is protected by copyright. All rights reserved.

Use of complementary and alternative medicine and low quality of life associate with the need for psychological and psychotherapeutic interventions in inflammatory bowel disease

Introduction

Patients with inflammatory bowel disease (IBD) suffer from various symptoms, impairing their quality of life and often affecting psychosocial issues. This may lead to the need for additional psychological care. This study investigated patients' subjective need for integrated psychosomatic support and psychotherapy and indicators for it.

Materials and methods

This is a cross‐sectional multicentre study in Austrian IBD patients who were in routine care at 18 IBD outpatient clinics. Patients filled in an anonymous, validated questionnaire (Assessment of the Demand for Additional Psychological Treatment Questionnaire [ADAPT]) assessing the need for psychological care. The ADAPT gives two separate scores: the need for integrated psychosomatic support and for psychotherapy. In addition, health‐related quality of life and the use of complementary and alternative medicine as well as clinical and socio‐demographic variables were queried. Multivariable regression analysis was performed to estimate the effect of the previously mentioned variables on the need for additional psychological care.

Results

Of 1286 patients, 29.7% expressed a need for additional psychological care, 19.6% expressed a need for integrated psychosomatic support and 20.2% expressed a need for psychotherapy. In the multivariable analysis, the two strongest indicators for the need for both types of psychological care were the use of complementary and alternative medicine (for integrated psychosomatic support: odds ratio = 1.64, 95% confidence interval 1.13–2.39, p = 0.010; for psychotherapy: odds ratio = 1.74, 95% confidence interval 1.20–2.53, p = 0.004), and a low health‐related quality of life score (for integrated psychosomatic support: odds ratio = 0.95, 95% confidence interval 0.94–0.96, p < 0.001; for psychotherapy: odds ratio = 0.96, 95% confidence interval 0.94–0.97, p < 0.001).

Discussion

About 30% of the Austrian IBD patients expressed a need for integrated psychosomatic support and/or psychotherapy. The most important indicators for this need were the use of complementary and alternative medicine and low quality of life.

What is already known?

Despite ongoing improvement of treatment options, patients may not respond to treatment or may develop side effects. Due to this burden of disease, patients may also suffer from psychological symptoms, such as depression

In our previous study in 2008, we found that 31% of patients with inflammatory bowel disease (IBD) expressed a subjective need for psychological interventions

What are the significant and/or new findings of the study?

Despite improvements in therapy, around 30% of patients with IBD express a subjective need for psychological interventions

This subjective need for psychological interventions is associated with complementary and alternative medicine use and low quality of life

Clinical Practice of Adalimumab and Infliximab Biosimilar Treatment in Adult Patients With Crohn's Disease

The introduction of tumor necrosis factor (TNF) inhibitors has significantly changed the treatment landscape in Crohn's disease (CD). The overall therapeutic achievements with TNF inhibitors such as infliximab, adalimumab, and certolizumab pegol paved the way to push the boundaries of treatment goals beyond symptomatic relief and toward cessation of objective signs of inflammation, including endoscopic remission. Even though these agents are widely used for the treatment of moderate to severe CD, heterogeneity still exists in translating evidence-based guidelines on the use of anti-TNF agents into actual treatment algorithms in CD. This might be due to several reasons including disparities in health expenditure policies; lack of harmonization between countries; and variations in assessment of disease severity, use of disease monitoring tools, or application of treatment targets by physicians. With the advent of biosimilars, patent-free versions of reference biologics are now available to minimize health inequalities in drug availability. In this context, this article aims to provide practical clinical guidance for the use of infliximab and adalimumab biosimilars in patients with moderate to severe CD by outlining different clinical scenarios that patients may encounter during their treatment journey.
